conform to IEE regulations. RF Address Code Setting, if
there is another user nearby, e.g. in the next dwelling, you
receiver may be operated in error by their transmitter. You
may select a different RF address code to prevent this. (see
EN encoding section).
NOTE: do not fi x the receiver in a permanent way to the
boiler casing.
INSTALLATION OF TRANSMITTER
The receiver and the transmitter are delivered already
coupled therefore the encoding procedure is not necessary
at the installation. In case it is required to encode the trans-
mitter and the receiver, this operation should be done while
the receiver and the transmitter are still very near (see the
encoding instructions).
Before fi xing the transmitter check that the radio signal is
active (if there is no communication the receiver will blink
red or green irregularly.
Because the transmitter uses radio waves to communicate
with the receiver, you should also bear in mind that metallic
objects can weaken or defl ect radio signals: this includes
steel reinforced walls, fi ling cabinets, kitchen appliances,
mirrors, etc. The range of the Radiostat is 40 metres in
open air, and 20 metres inside buildings, dependent on RF
obstructions as mentioned above.
Position the Radiostat on a wall surface away from obstruc-
tions and direct heat sources or draughts, in a room that is
warmed by the heating system. The fi xing of the transmitter
can be done either with screws and wall plugs or with the
double side adhesive depending on the wall surface quality
(both supplied). See the side diagram as reference to drill the
wall. Distance between 2 holes is 60 mm, drill hole dia. 5 mm.
In the case of using wall plugs, the transmitter box must be
as it contains electrostatically sensitive components.
FUNCTIONS
The weekly thermostat has the following functions:
• Room thermostat: the internal temperature sensor de-
tects the temperature and, comparing with the set point,
switches ON or OFF the heating request (according the
programmed timings). The temperature sensor is located
on the lower side of the item.
• Time: on the display it is possible to set and read the time
(weekly hours display mode)
• Programming timing: it is possible to select the desired
ON or OFF heating times. The programming is possible
during one week 24-hours and the minimum time seg-
ment is one hour.
• Status mode: AUTO, PARTY, OFF: Select AUTO mode if
timed ON/OFF period are required. Select PARTY mode
for constant ON (24-hours). Select OFF mode for heating
OFF (summer mode). Note: summer/winter selection is
better to be selected on the main boiler dashboard.
• ADVANCE functions: the pre-programmed heating pat-
tern is advanced to the next ON (or OFF) period

open to fi x the screws to the wall
plugs from inside the box. The
opening of the transmitter must be
done pressing gently the lower
button and leverage on the upper
side. Fit the supplied two batteries
inside the transmitter with the dir-
ection as indicated internally.
WARNING: Do not touch the prin-
ted circuit board of the transmitter
